Fanuc A16B-2201-0133 Memory (SRAM / BMU) Board. This PCB is Fanuc’s own replacement for the BMU boards fitted onto Fanuc series 6 and 11 control system. It has 256KB of storage and run and sits between the earlier BMU board capacity of 128KB and the 512KB boards for both the FS6 and FS11 respectively.
DNC offer their own replacements to the BMU bubble memory units that were fitted on the series 6 and 11 as well as having most of the original memory cards, including all A87L series FANUC BMU PCB’s for SYSTEM 6, 11 and 15 controls. Hence we can offer 128Kb / 512Kb solutions for the Fanuc 6, and up to 2MB for Fanuc 11 control systems.
